摘要: 以三峡库区优质柑橘产业带建设土地整理模式研究为目标,以重庆市万州区甘宁镇永胜等两个村土地整理项目(标准化柑橘园)为例,从工程、生物技术方面探讨了改土和配套农业产业化基础设施建设。研究表明:以三峡库区优质柑橘产业带建设目标的土地整理模式必须立足库区复杂多样的立地条件和生态-经济功能差异,配套服务早、中、晚熟不同柑橘品种产业化的改土、田间道路、排灌体系工程,重视改土过程耕作层保护、土壤改良与培肥,以及路、水、林的可持续生态化建设。

Abstract: Taking a land consolidation project for construction of citrus industrial belt in Wanzhou, Chongqing as an example, this paper discussed how land consolidation project could advance agricultural industry (construction of citrus industrial belt), by soil improvement and agricultural infrastructure construction from engineering technology and biological technology. The results suggest that pit planting method is suitable for dry land with deeper soil horizon, while trench planting method is suitable for dry land with thinner soil layer, and ditching-ridge planting method for paddy field. It is essential to dug trenches, back groove, and box groove at a distance of more than 1 m from citrus tree to get rid of the stagnant water in the soil. And, the main ditches among fields are supposed to construct according to landforms, so that surface water, soil water, and groundwater can discharge successfully. The pipelines as PVC and turnover pools are the crucial construction of irrigation systems. First of all, turnover pools connected to PVC pipes should be arranged at the location with high-pressure and large irrigation area. Secondly, the high-level pipes (Φ110mmPVC) and watershed area such as ponds, water reservoirs, natural ditches and irrigation canals are hooked up. Finally, portable water pumps and secondary pipes (Φ50mmPVC) should be matched. Aiming at constructing rural road network, the main field roads are supposed to arrange at a distance of no more than 200 m from the citrus trees, while the production roads with a width of 0.8~1.5 m should also be built at a distance of less than 75 m. In conclusion, both proper soil improvement measures and supporting agricultural infrastructure to fit in with the needs of different species of citrus are applied simultaneity for land consolidation model with the goal of construction of citrus industrial belt, depending on the complex and diverse conditions and different support services of ecological-economic functions in the Three Gorges Reservoir Area. Especially, more attention should be paid to soil plow layer protection, soil improvement and fertilizer, and sustainable ecological construction of rural roads and irrigation and drainage systems.
